Hi,
I have a script which isn't working in Mozilla based browser for some
reason. I'm trying to run two functions from the body onload tag and
it simply isn't happening.
I have a cascading menu, where the primary dropdown selection
determines the contents of a second dropdown. This is triggered by a
function in the onchange tag of the primarys select tag. When
triggered like this, the function and drop downs work fine. When
returning to the page I query a database to maintain state of the
primary dropdown and use the onload to trigger the function used in
the onchange to repopulate the second dropdown. As I say this works
fine in IE etc but not Mozilla based browsers.
Here's the code snippets. Anyone got any ideas?
In the header:
<script type="text/javascript">
function doOnload() {
selectInterests(form1)
preloadImages()
}
</script>
<script language="JavaScript">
function selectInterests(frm)
{
// Obtain the first dimension position of the currently selected
var i = frm.adv_category.selectedIndex;
var n = frm.adv_interests.selectedIndex;
if (i > 0){
// Inititalise the new adv_interests selection
frm.adv_interests.options.length = arrValInterests[i].length
- 1;
// Now select the the items associated with the selected
option
for (var j=1; j < arrValInterests[i].length; j++){
frm.adv_interests.options[j-1].text =
arrTextInterests[i][j];
frm.adv_interests.options[j-1].value =
arrValInterests[i][j];
}
frm.adv_interests.options[0].selected = true;
}
else{
// User has reselected the blank 'adv_interests' option
frm.adv_interests.options.length = 1;
frm.adv_interests.options[0].text ="--Please Select--
";
frm.adv_interests.options[0].value = "";
}
}
</script>
